Dynamic Evaluation of Ecological Environment Quality in Coastal Cities from the Perspective of Water Quality: The Case of Fuzhou City

Sustainability, Год журнала: 2023, Номер 15(15), С. 11537 - 11537

Urbanization has led to enormous pressure on the urban ecological environment, especially in coastal cities. It is important evaluate quality of We compared remote sensing-based index (RSEI) and water benefit-based (WBEI) indices Fuzhou City, selected WBEI assess changes environment City from 2000 2020 analyzed relevant land intensity. The results show that (1) outperforms RSEI evaluation study area, since takes into account efficiency can more accurately represent cities; (2) during 2000–2020, overall trend better, with nonsignificant decreasing areas western northern mountainous a significant increasing southeast coast; (3) different use types influence quality, forests man-made surfaces having good correlation WBEI. increase contributes improvement conversion high-intensity arable construction decreases quality. This provide basic reference for assessment experience

Land Use Land Cover Change Detection using Remote Sensing and Random Forest Model

Опубликована: Авг. 30, 2023

Land use and land cover (LULC) datasets for Jinan in 1992, 1998, 2002, 2006, 2011, 2017, 2022 were developed from Landsat images using the Random Forest (RF) classification approach. The relationships between social-economic, political factors time-series LULC data exam-ined periods 1992 2022. results showed effectiveness of RF method with time series images. Combined driving forces analysis, our research can effectively explain detailed change tra-jectories corresponding to different stages give new insights into pat-terns. show a significant increase impervious surface which opposite bare experienced huge decline declined by 95%, due urbanization rapid in-crease population. behind these changes are related population growth, economic development, climate change. Moreover, present employed Principal Components Analysis (PCA) methodology order understand relative significance disparate factors. analysis prove that economy (population, GDP) primary have an obvious impact on use/land surface, land, woodland, farmland, water distinct.

The coupling and coordinated relationship between the ecological environment carbon emissions is critical to sustained development of human society. remote sensing eco-index (RSEI) model has been applied assessment monitoring quality, but RSEI neglects air pollution, thus this study introduced aerosol optical depth (AOD) into index system constructed a novel ARSEI evaluate quality analyze spatial-temporal changes in energy-related emission (ECE) at county level China. Additionally, we further investigate local ECE China by using coupled coordination (CCD). outcomes showed that: (1) Compared with RSEI, widened gap east west along Heihe-Tengchong line; (2) value was significantly increased 24.70% areas China, mainly Northeast Plain, Loess Plateau, Tarim Basin. decreased 5.35% Qinghai-Tibetan northern part Tianshan Mountains, eastern coastal cities, central urban agglomerations; (3) dispersed from 2000 2017, an average annual increase > 0.3 megatons 354 counties, densely distributed agglomerations, sporadically some western cities China; (4) CCD distribution “west-low-east-high” pattern, upward trend majority surveyed counties (2,241), downward (171) southwest, south, Based on these results, recommendations are proposed above levels for sustainable economy ecology.

Ecological politics towards the protection of Alas Purwo National Park based on local wisdom

Malaysian Journal of Society and Space, Год журнала: 2023, Номер 19(4)

Опубликована: Ноя. 30, 2023

Alas Purwo National Park is a nature conservation area with natural ecosystem located in Banyuwangi Regency, developed for recreational, educational and purposes. Conservation management requires an ecological political approach to examine each actor's role resource management. In reality, policy makers have not been optimal managing areas because they are unable implement policies properly. This research used case study analyze cases about the of implementing related forest conservation. Data documents collected studies from Office. collection this direct observation field, in-depth interviews, documentation. analysis using interactive models consists three lines activities, data reduction, presentation, conclusions. qualitative research, whole process goes together. Findings showed that by policymakers views humans as source all values. Forest based on local wisdom must be placed mechanism through socio-cultural institutional rooted generations. interest inserted into national governments form As analytical knife dissect ecology approach, mapping problems how overcome them. Minimizing risk disasters climate change so far government community around buffer village had sensitivity sustainability resources. They only see it perspective economic benefits without understanding forests deposits preserved. Keywords: Park, politics,

LAND USE AND HABITAT QUALITY PREDICTION BASED ON MULTI-SCENARIO SIMULATION: A CASE STUDY OF JIAOZUO, CHINA

Applied Ecology and Environmental Research, Год журнала: 2023, Номер 21(6), С. 5753 - 5769

Опубликована: Янв. 1, 2023

To promote sustainable urban development, it is essential to assess the impacts of expansion on land-use change and habitat quality.Based data from four periods land use in Jiaozuo City (1990City ( , 2000City 2010City 2020)), China, this study used CA-Markov InVEST models create multi-scenario projections 2030, 2040 2050 quality status, respectively.The results showed that, 1990 2020, construction a trend continuous expansion, with an increase 57.75%, areas cultivated land, forested grassland, water area decreasing trend, decreases 5.34%, 9.75%, 10.37% 33.42%, respectively.In simulation three scenarios, did not experience any major changes next thirty years, indices were, descending order, ecological priority scenario, natural development scenario economic scenario.Predicting great importance for efficient utilization resources Jiaozuo.
